If you increase the sigma (e.g. to 2), the shape becomes wider. However,
the peak will become smaller. That is a necessary part of it being a
probability distribution.

You can scale it to force it to have a peak of 1.0:

plot Gauss(x,70,2)/Gauss(70,70,2)

but that is then not a normal distribution (or any sort of
distribution). 

Are you sure you want a probability DENSITY function? The cumulative
probability distribution does have 1 as its (asymptotic) maximum.
